I think I would be wary of it anyway thank you. But I do know it is possible to detect such high voltage by moving the back of a hand close enough to feel the electrostatic charge attracting the hairs on the back of the hand, before being close enough to get a discharge. perhaps this is an area where the female engineers among us are slightly disadvantaged :) -- http://www.piclist.com hint: The PICList is archived three different ways.
